Some suggestions are given in these pages. Feel free to modify as per your needs. The children should not be expected to read these pages. At the initial stages the pictures are used to talk to the children and the story is narrated by the teacher. Children are expected to read only the letter related to one sound, for example, 'b' at the initial stages. The same book can be used in Class I or II for reading purposes when the children have learnt all the sounds, the CVC words as well as the double letter words and diphthongs.
